I use Antirelay to allow me to check RBLs and trash messages. SMTPRCV blocks
those messages "at the door", which means that the message never gets into
my system. I've seen too many good messages trapped by RBLs to want to do
that. (I use Trash Finder [of course!] to eliminate the majority of messages
that are junk. TF runs in front of the Antirelay plugin, so it is only
serving as a backstop to catch the rare stuff that TF doesn't catch.) I
*don't* use Antirelay to trap relays; I let SMPTRCV do that. (Although
Antirelay checks for relays, none should be able to reach it, and indeed
I've never seen one stopped by it since I installed SMPTRCV.)

I think it just overrides the blacklist; I checked this fairly carefully in
the most recent version of the source code that I have. I would like to use
the bad user rejection, but I can't because I have to allow mail to be
delivered from our secondary mail server (maintained by our upstream ISP). I
don't want to block that mail unless it is really bad (that is, blocking
relays is OK, but not for bad users or spam traps). Otherwise, good mail
that might have ended up there for whatever reason might get blocked, which
would completely defeat the purpose of the secondary.
Klint, is it possible to get a "gateway" setting that would list IPs that
would tunnel in with minimal checks?

Which is why I'd like to be able to use the bad user filter in SMTPRCV! TF
is deleting the junk as fast as it comes in, but I fear the volume is going
to overwhelm my connection (and impact the users of the web server that's on
the same machine).
